LC Highpass Pi

Library

Description

The LC Highpass Pi block models the LC highpass pi network described
in the block dialog box, in terms of its frequency-dependent S-parameters.

For each inductor and capacitor in the network, the block first
calculates the ABCD-parameters at each frequency contained in the
vector of modeling frequencies. For each series circuit, A = 1, B = Z,
C = 0, and D = 1, where Z is the impedance of the
series circuit. For each shunt, A = 1,
B = 0, C = Y,
and D = 1, where Y is
the admittance of the shunt circuit.

The LC Highpass Pi block then cascades the ABCD-parameters for
each circuit element at each of the modeling frequencies, and converts
the cascaded parameters to S-parameters using the RF Toolbox™ abcd2s function.

See the Output Port block reference
page for information about determining the modeling frequencies.

The LC highpass pi network object is a two-port network as shown
in the following circuit diagram.

[L1, L2, L3,
...] is the value of the 'L' property, and [C1,
C2, ...] is the value of the 'C' property.

Dialog Box

Main Tab

Inductance (H)

Vector containing the inductances, in order from source to load,
of all inductors in the network. The inductance vector must contain
at least two elements. All values must be strictly positive.

Capacitance (F)

Vector containing the capacitances, in order from source to
load, of all capacitors in the network. Its length must be equal to
or one less than the length of the vector you provide in the Inductance parameter.
All values must be strictly positive.
